  • Radar absorption material thickness testing device
    Patent number: 5012248
    Abstract: The invention is a device for determining the thickness of radar absorption material coatings. The device comprises a radiating element assembly 22 for transmitting RF energy to and recovering reflected RF energy from the coating. A source of frequency modulated RF signal, including an FM ramp generator assembly 11, buffer amplifier assembly 13 and Gunn oscillator 16, is provided. A ferrite circulator 20 is adapted to direct the source of modulated RF signal to the radiating element assembly 22 and the reflected RF energy to a detector assembly. The detector assembly includes a Schottky detector 24, a video amplifier assembly 40, a converter/driver assembly 42, and a digital display 44, and is adapted to sense the reflected RF energy from the coating and provide a visual display in the form of a voltage inversely proportional to the amount of the reflected RF energy.
